TYPOGRAPH Application filed December To all 10 7mm it may concern Be itknown that 1, WILLIAM A. READE, a citizen of the United States, and aresident of Evanston, county of Cook, and State of Illinois, haveinvented a new and useful lmprovement in Typograph hlechanisin, of whichthe following is a specification, the principle of the invention beingherein explained, and the best mode in which ll have contemplatedapplying that principle so as to distinguish it from other inventions.

The present improvements, relating, as indicated, to typographmechanism, have more particular regard to the provision of means wherebyslugs or lines of type'may be cast on which the characters are inclined,as in italics. I am aware that attempts have heretofore been mac-e toadapt the Mergenthaler linotype and other similar typograph machines forthe casting of type bars of this sort, but no commercially successfuldevice has even been achieved.

. The present invention, accordingly, has at its object the provision ofa novel form of matrix bar, or matrix as it is commonly termed, whichmay be utilized in connection with the regular feeding and assembling.mechanism of a standard linotype or equivalent'machine. To theaccomplishment of the foregoing and related ends, the invention, then,consists of the means hereinafter fully described and particularlypointed out in the claims, the annexed drawing and the followingdescription setting forth in detail certain mechanism embodying theinvention, such disclosed means constituting, however, but one ofvarious mechanical forms in which the principle of the invention mayused.

In said annexed drawing .Fig. 1 is a front elevation of those parts of atypical linotype machine in connection with which my present improvementmay be employed; Fig. 2 is a transverse section, on a larger scale,throughthe mold and adjacent parts, the plane of the section beingindicated by the line 22, Fig. 1; Fig- 8 is a front view'of an assembledline of inatrices as collected and held in position for casting, similarto that shown in cross-section in Fig. 2; Fig l is a rear view of ashorter assembly of matrices showing the faces that carry the intagliotype characters, such matrices appearing in their initial position, i.e. as first assembled; Fig. 5 a

view similar to Fig. l, but showing the matrices in a subsequent stageof their assembly,

ready for casting; and Fig. 6 is a view of a single matrix on a largerscale than those shown in Figs. s and 5.

In the typical construction of linotype machine shown in Fig. 1', thefont of special matrices employed in the casting of italics will benormally contained in suitable sections or compartments of themagazine 1. From the latter they are received on the assembling belt 2,one at a time, and are assembled side by side in line, as shown in Fig.4. As they are thus assembled, such line of matrices is deliveredhorizontally from the elevator through. the so-called intermediatechannel 3 from the elevator 4, after the latter has been raised. Fromthe channel 3 the line of matrices is transferred to a second elevator5, which is raised into the position ferred to, as is also the mechanismwhereby the matrices are subsequently lifted to the distributingmechanism; thence to be delivcred again 'to the magazine 1. Since thepresent invention relates primarily to the form of the matrices and themanner in which they are assembled in line in the channel 3, andsubsequently disposed for casting adjacent the mold 6, it is not deemednecessary to further describe the unrelated parts of the generalmachine.

As shown in Fig. 2, in which a single matrix 10 appears held in propercasting against the face of the mold 6, such matrix in side elevationresembles those in familiar use in commercial linotype work, such matrixconsisting of a flat plate with an intaglio character 11 in its edgethus juxtaposed to the slot 12 in the mold. The character impression 11in the case in hand is shown as formed in a depression 13 in such edgeof the matrix, such depression being of greater width than the slot 12sons to provide an enlarged body or head on the finished slug to supportthe raisedcharacter impressions when the cast is made. The sides of thedepressions 13, as shown in Figs l, 5 and 6, are not, as ordinarily,disposed at composing such matrix, are formed with other surfaces 15,1:3, that are parallel with the sides of the recess 13 in the casting ofthe slate. So, too, the shoi' de'rs l6 and 17 adjacent the upper and 10*er edges of the )late respectively are forinedon their inner faces withsurfaces 16", parallel with said surfaces 14, and with surfaces 16",parallel with said surfaces 15, it being by us of such shoulders thatthe matrices are sue tained as they pass through channel 3.

In the preliminary assembly of the matrices as they are received fromconveyor'2 and lined up on elevator l they rest on the normal faces 14,as shown in Fig. l, in which position the character depressions areobviously not properly disposed to form a. com

.posite mold of the desired kind; however, by

tilting such assemblyo'f matrices so that the inclined surfaces 15 arebrought into alignment, as shown in Fig. 5, the character depressionsare then brought into proper line to form such composite matrix. For.the

1 purpose of thus tiltingor inclining. the mat-- rices, a wedge block inthe form of a blank matrix 20, having faces that incline at the properangle to each other, 1s introduced at each end of the assembly, so thatupon clamping the assembly between two abutments 21 and 22, as shown inFig. 3,, having faces normal to the line of assembly, all of thematrices bearing character impressions are tilted to the predeterminedangle. For the, purpose oi spacing, other blank matrices 23, havingparallel sides, may be introduced where desired in the line of assembledmatrices, as shown in Figs. 4: and 5.

By reason of the angu-larly related faces 14 and 15 on the respectivematrices, and the correspondingly angularly related faces 16" and 16* onthe shoulders 16, the tilting of the assembled line. may take placeeither while such matrices are resting on a flat surtace or aresustained, by means of such The char pression.

chine being illustrative only, Obviously such assembling may beaccomplished directly by hand either in channel 3 or elevator 5 of suchmachine, or in other equivalent holder, and then after tiltingthematrices and clamping them together in assembled condition, the slugmaybe cast therefrom in any suitable casting machine. 'ltwill fur therbe understood that it required solely for use with my improved matrices,the clamping abutments may have theirfaces inclined, just as though thewedge-shaped plates 2 were integral therewith, and the use of suchplates thus dispensed with. 1

I t will be understood, further that no limitation is to be implied inthe field of use of the present invention to the particular typegraphmachine'hereinbeitore specifically referred to but that the improvementsinquestion may be employed in conjunction with various type-bar castingmachines at present on the market, as, for example, with the well-knownLudlow typograph.

(l ther modes of applying the principle ofmy invention maybe employedinstead of, the one explained, change being made'as regards the detailsherein disclosed, provided the steps or means stated by any of thefollowing claims or the equivalent of such stated steps or means beemployed.

I therefore particularly point out and distinctly claim as my invention.
